NFX250 Device Hardware Overview

The JuniperNetworksNFX250NetworkServicesPlatformcomprises the JuniperNetworks

NFX250 devices, which are Juniper Network’s secure, automated, software-driven

customerpremisesequipment (CPE)devices thatdeliver virtualizednetworkandsecurity

services on demand. Leveraging Network Functions Virtualization (NFV) and built on the

JuniperCloudCPEsolution,NFX250enables serviceproviders todeployandservice chain

multiple, secure, high-performance virtualized network functions (VNFs) as a single

device. This automated, software-driven solution dynamically provisions new services

on demand.

This topic covers:

• NFX250 Hardware on page 3

• System Software on page 4

NFX250Hardware

NFX250 devices are available in three compact 1 Umodels that provide VNF and Packet

Forwarding Engine capacity, and a rich set of Layer 2 and Layer 3 features.

NFX250 device has Eight 1-GbE network ports, two 1-GbERJ-45 portswhich can be used

aseitheraccessportsorasuplinks, twoSFPports, twoSFP+ports, andonemanagement

port. NFX250device has a 1U form factor and comeswith built-in fans andpower supply.

Figure 1: NFX250 Port Panel

NFX250 device can be used as:


• An integrated branch router and switch, extensible with VNFs.

• A CPE for service providers.

• A secure router for distributed enterprises.

SystemSoftware

NFX250 devices use the Junos Device Manager (JDM) for virtual machine (VM) lifecycle

and device management, and for a host of other functions. The JDM CLI is displayed

when you log in to the NFX250 device. The JDM CLI is similar to the Junos OS CLI in look

and provides the same added-value facilities as the Junos OS CLI.

You canmanage the device by using the JDM CLI, accessible through the console and

the out-of-bandmanagement ports on the device.

Efficient device operation requires proper site planning andmaintenance and proper

layout of the equipment, rack or cabinet (if used), and wiring closet.

To plan and create an acceptable operating environment for your device and prevent

environmentally caused equipment failures:

• Keep the area around the chassis free from dust and conductive material, such as

metal flakes.

• Followprescribedairflowguidelines toensure that thecoolingsystemfunctionsproperly

and that exhaust from other equipment does not blow into the intake vents of the

device.

• Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent

damaging the equipment. Static discharge can cause components to fail completely

or intermittently over time.

• Install the device in a secure area, so that only authorized personnel can access the

device.

Table 14: Cabinet Requirements for the NFX250 Device (continued)

GuidelinesCabinet Requirement

Whenyoumount the switch inacabinet, ensure that ventilation through thecabinetis sufficient to prevent overheating.

• Ensure that the cool air supply you provide through the cabinet adequatelydissipates the thermal output of the switch (or switches).

• Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinetwithout recirculating into the switch. An open cabinet (without a top or doors)that employs hot air exhaust extraction from the top allows the best airflowthrough the chassis. If the cabinet contains a top or doors, perforations in theseelements assist with removing the hot air exhaust.

• Install the switch in the cabinet in a way that maximizes the open space on theside of the chassis that has the hot air exhaust.

• Route and dress all cables to minimize the blockage of airflow to and from thechassis.

• Ensure that the spacing of rails and adjacent cabinets allows for the properclearance around the switch and cabinet.

• A cabinet larger than theminimum required provides better airflow and reducesthe chance of overheating.

SFP+ Direct Attach Cables for NFX250 Devices

Small form-factor pluggable plus transceiver (SFP+) direct attach copper (DAC) cables,

also known as Twinax cables, are suitable for in-rack connections between servers and

switches. They are suitable for short distances of up to 23 ft (7 m), making them ideal



for highly cost-effective networking connectivity within a rack and between adjacent

racks.

This topic describes:

• Cable Specifications on page 67

• Standards Supported by These Cables on page 69

Cable Specifications

NFX250devices supportSFP+passiveDACcables. ThepassiveTwinaxcable is a straight

cable with no active electronic components. NFX250 devices support 1 m, 3 m, and 5m

long SFP+ passive DAC cables.

NOTE: We recommend that you use only SFP+ DAC cables purchased fromJuniper Networks with your Juniper Networks device.

CAUTION: If you face a problem running a Juniper Networks device that usesa third-partyopticor cable, the JuniperNetworksTechnicalAssistanceCenter(JTAC) can help you diagnose the source of the problem. Your JTAC engineermight recommendthatyoucheckthethird-partyopticorcableandpotentiallyreplace it with an equivalent Juniper Networks optic or cable that is qualifiedfor the device.

The cables are hot-removable and hot-insertable: You can remove and replace them

without powering off the switch or disrupting switch functions. A cable comprises a

low-voltage cable assembly that connects directly into two SFP+ ports, one at each end

of the cable. The cables use high-performance integrated duplex serial data links for

bidirectional communication and are designed for data rates of up to 10 Gbps.

Table 24 on page 68 describes the cable specifications.

Understanding NFX250 Devices Fiber-Optic Cable Signal Loss, Attenuation, andDispersion

To determine the power budget and power margin needed for fiber-optic connections,

you need to understand how signal loss, attenuation, and dispersion affect transmission.

The NFX250 devices use various types of network cable, including multimode and

single-mode fiber-optic cables.

• Signal Loss in Multimode and Single-Mode Fiber-Optic Cables on page 70

• Attenuation and Dispersion in Fiber-Optic Cable on page 71

Signal Loss in Multimode and Single-Mode Fiber-Optic Cables

Multimode fiber is large enough in diameter to allow rays of light to reflect internally

(bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs

as light sources. However, LEDs are not coherent light sources. They spray varying

wavelengths of light into themultimode fiber, which reflects the light at different angles.

Light rays travel in jagged lines through amultimode fiber, causing signal dispersion.

When light traveling in the fiber core radiates into the fiber cladding (layers of lower

refractive indexmaterial in close contact with a core material of higher refractive index),

higher-ordermode loss occurs. Together, these factors reduce the transmission distance

of multimode fiber compared to that of single-mode fiber.

Single-mode fiber is so small in diameter that rays of light reflect internally through one

layer only. Interfaceswith single-mode optics use lasers as light sources. Lasers generate

a singlewavelength of light, which travels in a straight line through the single-mode fiber.

Compared to multimode fiber, single-mode fiber has a higher bandwidth and can carry

signals for longer distances. It is consequently more expensive.



For information about the maximum transmission distance and supported wavelength

range for the types of single-mode andmultimode fiber-optic cables that are connected

to the NFX250 devices, see “Pluggable Transceivers Supported on NFX250 Devices” on

page 41. Exceeding the maximum transmission distances can result in significant signal

loss, which causes unreliable transmission.

Attenuation and Dispersion in Fiber-Optic Cable

Anoptical data link functionscorrectlyprovided thatmodulated light reaching the receiver

has enough power to be demodulated correctly. Attenuation is the reduction in strength

of the light signal during transmission. Passivemedia components such as cables, cable

splices, and connectors cause attenuation. Although attenuation is significantly lower

for optical fiber than for other media, it still occurs in both multimode and single-mode

transmission. An efficient optical data link must transmit enough light to overcome

attenuation.

Dispersion is the spreading of the signal over time. The following two types of dispersion

can affect signal transmission through an optical data link:

• Chromatic dispersion, which is the spreading of the signal over time caused by the

different speeds of light rays.

• Modal dispersion,which is the spreading of the signal over time causedby thedifferent

propagation modes in the fiber.

For multimode transmission, modal dispersion, rather than chromatic dispersion or

attenuation, usually limits the maximum bit rate and link length. For single-mode

transmission,modaldispersion is nota factor.However, at higherbit ratesandover longer

distances, chromatic dispersion limits the maximum link length.

An efficient optical data linkmust have enough light to exceed theminimum power that

the receiver requires to operate within its specifications. In addition, the total dispersion

mustbewithin the limits specified for the typeof link inTelcordiaTechnologiesdocument

GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU)

document G.957.

When chromatic dispersion is at the maximum allowed, its effect can be considered as

a power penalty in the power budget. The optical power budget must allow for the sum

of component attenuation, power penalties (including those from dispersion), and a

safety margin for unexpected losses.


Calculating the Fiber-Optic Cable Power Budget for an NFX250 Device on page 71•


Calculating the Fiber-Optic Cable Power Budget for an NFX250 Device

Calculate the link's power budget when planning fiber-optic cable layout and distances

to ensure that fiber-optic connections have sufficient power for correct operation. The

powerbudget is themaximumamountofpower the linkcan transmit.Whenyoucalculate



thepowerbudget, youuseaworst-caseanalysis toprovideamarginof error, even though

all the parts of an actual system do not operate at the worst-case levels.

To calculate the worst-case estimate for fiber-optic cable power budget (PB) for the

link:

1. Determinevalues for the link'sminimumtransmitterpower (PT)andminimumreceiver

sensitivity (PR). For example, here, (P

T)and(P

R)aremeasured indecibels, anddecibels

are referenced to 1 milliwatt (dBm).

PT= –15 dBm

PR= –28 dBm

NOTE: See the specifications for your transmitter and receiver to find theminimum transmitter power andminimum receiver sensitivity.

2. Calculate the power budget (PB) by subtracting (PR) from (PT):

–15 dBm – (–28 dBm) = 13 dBm

Calculating the Fiber-Optic Cable Power Margin for an NFX250 Device

Calculate the link's power margin when planning fiber-optic cable layout and distances

to ensure that fiber-optic connections have sufficient signal power to overcome system

losses and still satisfy the minimum input requirements of the receiver for the required

performance level. The power margin (PM) is the amount of power available after

attenuation or link loss (LL) has been subtracted from the power budget (PB).

When you calculate the powermargin, you use aworst-case analysis to provide amargin

of error, even though all the parts of an actual system do not operate at worst-case

levels. Apowermargin (PM) greater than zero indicates that thepowerbudget is sufficient

to operate the receiver and that it does not exceed themaximum receiver input power.

This means the link will work. A (PM) that is zero or negative indicates insufficient power

to operate the receiver. See the specification for your receiver to find the maximum

receiver input power.

Before you begin to calculate the power margin:



• Calculate the power budget. See “Calculating the Fiber-Optic Cable Power Budget for

an NFX250 Device” on page 71.

To calculate the worst-case estimate for the power margin (PM) for the link:

1. Determine the maximum value for link loss (LL) by adding estimated values for

applicable link-loss factors—for example, use the sample values for various factors

as provided in Table 26 on page 73 (here, the link is 2 km long andmultimode, and

the (PB) is 13 dBm):

Table 26: Estimated Values for Factors Causing Link Loss

Sample Link Loss (LL) Calculation ValuesEstimated Link-Loss ValueLink-Loss Factor

0.5 dBmMultimode—0.5 dBmHigher-ordermodelosses

0 dBmSingle-mode—None

0 dBmMultimode—None, if product ofbandwidth and distance is lessthan 500MHz/km

Modal and chromaticdispersion

0 dBmSingle-mode—None

This example assumes five connectors. Loss for fiveconnectors: 5 (0.5 dBm) = 2.5 dBm.

0.5 dBmConnector

This exampleassumes twosplices. Loss for twosplices:2 (0.5 dBm) = 1 dBm.

0.5 dBmSplice

This example assumes the link is 2 km long. Fiberattenuation for 2 km: 2 km (1 dBm/km) = 2 dBm.

Multimode—1 dBm/kmFiber attenuation

This example assumes the link is 2 km long. Fiberattenuation for 2 km: 2 km (0.5 dBm/km) = 1 dBm.

Single-mode—0.5 dBm/km

1 dBm1 dBmClock Recovery Module(CRM)

NOTE: For information about the actual amount of signal loss caused byequipment and other factors, see your vendor documentation for thatequipment.

2. Calculate the (PM) by subtracting (LL) from (P

B):

PB– LL = P

M

13 dBm – 0.5 dBm [HOL] – 5 (0.5 dBm) – 2 (0.5 dBm) – 2 km (1.0 dBm/km) – 1 dB

[CRM] = PM

13 dBm – 0.5 dBm – 2.5 dBm – 1 dBm – 2 dBm – 1 dBm = PM



PM= 6 dBm

Thecalculatedpowermargin is greater than zero, indicating that the link has sufficient

power for transmission. Also, the power margin value does not exceed themaximum

receiver input power. Refer to the specifications for your receiver to find themaximum

receiver input power.

Replacing Transceiver



Installing a Transceiver in an NFX250 Device

The transceivers for the NFX250 devices are hot-removable and hot-insertable

field-replaceable units (FRUs). You can remove and replace themwithout powering off

the device or disrupting device functions.

Before you begin installing a transceiver in anNFX250device, ensure that you have taken

the necessary precautions for safe handling of lasers (see “Laser and LED Safety

Guidelines andWarnings for the NFX250 Devices” on page 145).

Ensure that you have a rubber safety cap available to cover the transceiver.

To install a transceiver in a NFX250 device:

CAUTION: Toavoidelectrostaticdischarge (ESD)damage to the transceiver,do not touch the connector pins at the end of the transceiver.

1. Remove the transceiver from its bag.

2. Check to see whether the transceiver is covered by a rubber safety cap. If it is not,

cover the transceiver with a rubber safety cap.

WARNING: Do not leave a fiber-optic transceiver uncovered exceptwheninserting or removing a cable. The rubber safety cap keeps the port cleanand prevents accidental exposure to laser light.

3. If the port in which you want to install the transceiver is covered with a dust cover,

remove the dust cover and save it in case you need to cover the port later.

4. Using both hands, carefully place the transceiver in the empty port. The connectors

must face the device chassis.


CAUTION: Before you slide the transceiver into the port, ensure that thetransceiver is aligned correctly. Misalignmentmight cause the pins tobend, making the transceiver unusable. See Figure 25 on page 110 for thecorrect orientation for your device.

5. Slide the transceiver in gently until it is fully seated. See Figure 25 on page 110 for an

example of inserting an SFP or SFP+ transceiver.

6. Remove the rubber safety cap when you are ready to connect the cable to the

transceiver.

WARNING: Do not look directly into a fiber-optic transceiver or into theends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cablesconnected to transceivers emit laser light that can damage your eyes.

Maintaining Fiber-Optic Cables in an NFX250 Device

Tomaintain fiber-optic cables in NFX250 devices:

• When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over

the transceiver and on the end of the cable.

• Anchor fiber-optic cable toavoid stresson theconnectors.Whenattachinga fiber-optic

cable to a transceiver, be sure to secure the fiber-optic cable so that it is not supporting

its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the

connector.

• Donot bend fiber-optic cables beyond theirminimumbend radius. Bending the cables

beyond their minimum bend radius can damage the cables and cause problems that

are difficult to diagnose.

• Frequentpluggingandunpluggingof fiber-optic cables inandoutofoptical instruments

can damage the instruments, which are expensive to repair. Attach a short fiber

extension to the optical equipment. Any wear and tear due to frequent plugging and


Chapter 16: Maintaining and Replacing Fiber-Optic Cable

unplugging is then absorbed by the short fiber extension, which is easier and less

expensive to replace than the instruments.

• Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of

the transceiver or cable connector can cause loss of light, reduction in signal power,

and possibly intermittent problems with the optical connection.

Toclean the transceiver canal, useanappropriate fiber-cleaningdevice suchasRIFOCS

Fiber Optic Adaptor CleaningWands (part number 946). Follow the directions in the

Fire Safety Requirements

• Fire Safety Requirements on page 135

Fire Safety Requirements

In the event of a fire emergency, the safety of people is the primary concern. You should

establishprocedures for protectingpeople in theeventof a fire emergency, provide safety

training, and properly provision fire-control equipment and fire extinguishers.

In addition, you should establish procedures to protect your equipment in the event of a

fire emergency. JuniperNetworksproducts shouldbe installed inanenvironment suitable

for electronic equipment. We recommend that fire suppression equipment be available

in the event of a fire in the vicinity of the equipment and that all local fire, safety, and

electrical codesandordinancesbeobservedwhenyou install andoperateyourequipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, you should first turn power off to

theequipmentat the source. ThenuseaTypeC fire extinguisher,whichusesnoncorrosive

fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide

andHalotron™,aremosteffective for suppressingelectrical fires. TypeC fire extinguishers

displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire

on or around equipment that draws air from the environment for cooling, you should use

this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves

residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire

extinguishers). The primary ingredient in these fire extinguishers is monoammonium

phosphate,which is very sticky anddifficult to clean. In addition, in thepresenceofminute

amounts of moisture, monoammonium phosphate can become highly corrosive and

corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is

subject to premature failure and unreliable operation. The equipment is considered to

be irreparably damaged.


NOTE: Tokeepwarrantieseffective,donotuseadrychemical fireextinguisherto control a fire at or near a Juniper Networks device. If a dry chemical fireextinguisher is used, the unit is no longer eligible for coverage under a serviceagreement.

We recommend that you dispose of any irreparably damaged equipment in an

environmentally responsible manner.

Laser and LED Safety Guidelines andWarnings for the NFX250 Devices

NFX250 devices are equipped with laser transmitters:

• SFP and SFP+ transceivers are classified as Class 1 Laser Products (complies with 21

CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice 50, dated July

26, 2001) or Class 1 LED Products.

Observe the following guidelines and warnings:

• General Laser Safety Guidelines on page 145

• Class 1M Laser ProductWarning on page 146

• Class 1M Laser RadiationWarning on page 146

• Class 1 Laser ProductWarning on page 146

• Class 1 LED ProductWarning on page 147

• Laser BeamWarning on page 147

• Unterminated Fiber-Optic CableWarning on page 148

General Laser Safety Guidelines

When working around ports that support optical transceivers, observe the following

safety guidelines to prevent eye injury:

• Do not look into unterminated ports or at fibers that connect to unknown sources.

• Do not examine unterminated optical ports with optical instruments.

• Avoid direct exposure to the beam.

WARNING: Unterminated optical connectors can emit invisible laserradiation. The lens in the human eye focuses all the laser power on the


retina, so focusing the eye directly on a laser source—even a low-powerlaser—could permanently damage the eye.

• TN PowerWarning on page 162

General Electrical Safety Guidelines andWarnings

WARNING: Certain ports on the device are designed for use as intrabuilding(within-the-building) interfaces only (Type 2 or Type 4 ports as described inGR-1089-CORE) and require isolation from the exposedoutside plant (OSP)cabling. To comply with NEBS requirements and protect against lightningsurges and commercial power disturbances, the intrabuilding portsmust notbemetallically connected to interfaces that connect to theOSP or its wiring.The intrabuilding ports on the device are suitable for connection tointrabuilding or unexposed wiring or cabling only. The addition of primaryprotectors is not sufficient protection for connecting these interfacesmetallically to OSPwiring.

CAUTION: Before removing or installing components of a device, attach anelectrostatic discharge (ESD) grounding strap to an ESD point and place theother endof thestraparoundyourbarewrist. Failure touseanESDgroundingstrap could result in damage to the device.

• Install the device in compliance with the following local, national, and international

electrical codes:

• United States—National Fire Protection Association (NFPA 70), United States

National Electrical Code.

• Other countries—International Electromechanical Commission (IEC) 60364, Part 1

through Part 7.


• Evaluated to the TN power system.

• Canada—Canadian Electrical Code, Part 1, CSA C22.1.

• Locate the emergency power-off switch for the room in which you are working so that

if an electrical accident occurs, you can quickly turn off the power.

• Make sure that grounding surfaces are cleaned and brought to a bright finish before

grounding connections are made.

• Donotworkalone if potentially hazardousconditionsexist anywhere in yourworkspace.

• Never assume thatpower is disconnected fromacircuit. Always check thecircuit before

starting to work.

• Carefully look for possible hazards in your work area, such asmoist floors, ungrounded

power extension cords, andmissing safety grounds.

• Operate the device within marked electrical ratings and product usage instructions.

• To ensure that the device and peripheral equipment function safely and correctly, use

the cables and connectors specified for the attached peripheral equipment, andmake

certain they are in good condition.

You can remove and replace many device components without powering off or

disconnectingpower to thedevice, asdetailedelsewhere in thehardwaredocumentation

for this device. Never install an equipment that it appears to be damaged.





Action to Take After an Electrical Accident

If an electrical accident results in an injury, take the following actions in this order:

1. Use caution. Be aware of potentially hazardous conditions that could cause further

injury.

2. Disconnect power from the device.

3. If possible, send another person to get medical aid. Otherwise, assess the condition

of the victim, then call for help.








Prevention of Electrostatic Discharge Damage

Device components that are shipped in antistatic bags are sensitive to damage from

static electricity. Some components can be impaired by voltages as low as 30 V. You

can easily generate potentially damaging static voltages whenever you handle plastic

or foam packing material or if youmove components across plastic or carpets. Observe

the following guidelines to minimize the potential for electrostatic discharge (ESD)

damage, which can cause intermittent or complete component failures:

• AlwaysuseanESDgroundingstrapwhenyouarehandlingcomponents thatare subject

to ESD damage, andmake sure that it is in direct contact with your skin.

If a grounding strap is not available, hold the component in its antistatic bag (see

Figure 29 on page 159) in one hand and touch the exposed, bare metal of the device

with the other hand immediately before inserting the component into the device.

WARNING: For safety, periodically check the resistance value of the ESDgrounding strap. Themeasurementmust be in the range 1 through10Mohms.

• When handling any component that is subject to ESD damage and that is removed

from thedevice,make sure the equipment endof your ESDgrounding strap is attached

to the ESD point on the chassis.

If nogrounding strap is available, touch theexposed, baremetal of thedevice toground

yourself before handling the component.

• Avoidcontactbetween thecomponent that is subject toESDdamageandyourclothing.

ESD voltages emitted from clothing can damage components.

• When removing or installing a component that is subject to ESDdamage, always place

it component-side up on an antistatic surface, in an antistatic card rack, or in an

antistatic bag (see Figure 29 on page 159). If you are returning a component, place it in

an antistatic bag before packing it.
